Chemistry Question on Stoichiometry and Stoichiometric Calculations

Which has the maximum number of molecules among the following ?

A

44 g CO244\, g\, CO _{2}

B

48 g O348\, g \,O _{3}

C

8 g H28\, g\, H _{2}

D

64 g SO264\, g\, SO _{2}

Answer

8 g H28\, g\, H _{2}

Explanation

Solution

44 g CO2=144\, g \,CO _{2}=1 mol CO2=NACO _{2}=N_{A} molecules of CO2CO _{2}
48 g O3=148 \,g\, O _{3}=1 molO3=NA O _{3}=N_{A} molecules of O3O _{3}
8 g H2=48\, g \,H _{2}=4 mol H2=4×NAH _{2}=4 \times N_{A} molecules of H2H _{2}
64 g SO2=164 \,g\, SO _{2}=1 mol SO2=NASO _{2}=N_{A} molecules of SO2SO _{2}
